Pull up following revision(s) (requested by lukem in ticket #788):
distrib/sets/lists/etc/mi: revision 1.160
UPDATING: revision 1.143 via patch
Don't mark /etc/namedb/named.conf as "obsolete" since that will cause
a file that has end-user configuration to be unconditionally removed.
Instead, remove the entry from the set list, and add a note to UPDATING
reminding users of MKUPDATE=yes to manually rectify the problem in
their DESTDIR.
The "named" fix in postinstall(8) will migrate /etc/namedb/named.conf
to /etc/named.conf if the latter doesn't exist.
(The need for these style of migrations was why I implemented postinstall(8)
in the first place.)
